Maverick police detective Creegan is the newest member of London's Organised and Serial Crime Unit (OSC),an elite, rapid-response crime squad. The OSC uses their diverse crime-fighting skills to bring justice to society. Along with his stalwart partner D.I. Susan Taylor, Creegan squares off against some of England's most dangerous criminals; a serial murderer of children, a killer intent on murdering hospital patients, and a cyber-criminal who lures young Web-surfers with a Gothic fantasy game and manipulates them into committing violent crimes.
